A U.S. health panel may soon make HIV testing as standard a practice as checking cholesterol levels, a move that would fundamentally change how the virus is detected and treated. The U.S. Preventive Services Task force, a government-backed group of clinicians and scientists, is expected to make a new recommendation on HIV screening available for public comment before the end of the year. Health officials close to the panel, speaking on condition of anonymity, see it making a positive recommendation for routine screening, updating their current position, issued in 2005, which leaves the decision up to doctors.
